AUDIBLE CULINARY ALARM.

Application filed August 26, 1915.

To all whom it may concern Be it known that I, ADA ROBERTS, a citizen ofthe United States, residing at Yerkes in the county of Montgomery andState of Pennsylvania, have invented certain new and useful Improvementsin Audible Culinary Alarms, of which the following is a specification.

This invention relates to an audible culinary alarm or signaling deviceof the common hour-glass type and has for its object to increase thescope and delicacy of adjustment of such articles to more completelymeet the individual judgment and taste of any particular housewife, saidobject being accomplished by the construction, arrangement andcombination of parts hereinafter more particularly set forth anddescribed.

In the accompanying drawings: Figure 1 represents a perspective view ofan alarm embodying my invention; and Fig. 2 rep resents across-sectional view of the hour glass slightly above the narrowest partof its communicating passage or neck.

Referring now in detail to the drawing, 1 designates a supporting frameof a single piece of wire having a horizontal lower rod 2 from which thealarm bell 3 is suspended. Extending upward from this rod 2 it istwisted on itself to form bearings 10 for the arms 4 of the yoke 55.From the bearings 10 the frame extends upward and backward at a slightangle and is U-shaped in form to provide a rest for the stem of thebell-striker or clapper 6.

The hour-glass shaped emery container 7 is mounted in any suitablemanner in wire frame 8 consisting of one piece of wire, which issoldered to yoke 5 at their points of intersection, one of the ends ofthe wire of said frame being carried up and bent slightly forward,forming a stem to receive fixedly on its tip the striker 6, holding thesame slightly in advance of the longitudinal central line of thehour-glass, thus making it slightly top heavy. Stops 9 are fixed on thearms 1 to bear against the inner faces of the bearings 10 and preventthe arms 1 fro-m slipping out of said bearings.

hen a sufficient quantity of emery has passed from the upper part a. ofthe hourglass to the lower part b to cause the hourglass to assume avertical position, the striker 6 will be slightly in advance of thevertical central line of the hour-glass, mak- Specification of LettersPatent.

ing it top-heavy and causing it to turn on its arms 1 in bearings 10,thereby bringing the striker 6 into contact with bell 2 and sounding thealarm. The position of parts a and b of the hourglass will then beinverted and the emery or other suitable material will flow back intopart a from part a, when the device will be readyfor use again.

The hour-glass container 7 is provided, at its narrowest part 15 of thepassage between the two members a and b, with a transverse slot and, toregulate the flow of emery from part a to part b, a plate 11 ispivotally mounted at the narrowest part 15 of the passage between thesetwo parts in said transverse slot by means of a rivet 12 passing througha lug 13 on the exterior face of the hour-glass at this point, this lugbeing divided by said transverse slot in which the plate oscillates.This plate 11 is provided with a regularly tapering arcuate slot 14adapted to be brought under the narrowest part of the passage at 15, asshown in Fig. 2. The length of this slot 14, as shown in Fig. 2, is fivetimes the diameter of the passage at its narrowest point 15, and themaximum width of the slot 14 is equal to the diameter of said passage atsaid point.

The top of the exposed part of the plate 11 is provided with a series offive numerals and the edge of the upper part of lug 13 is brought to afine line to act as an index, thus when the plate 11 is moved by arm 16so that numeral 1 registers with the thin edge of the lug 13 it willindicate that the plate is in position to allow the maximum flow, whenthe numeral 5 so registers it will indicate that the plate is inposition to allow only the minimum flow, and when registering withintermediate numerals will indicate that the plate is between these twoextremes. As this arcuate tapering slot 1-1 is one continuous opening itwill be evident that the plate may be set so that the thin edge of lug13 will register with any one of the numerals or may be set at anydesired point between any two numerals to secure any desired rate offlow within the range of the slot 14, thus securing a great degree ofdelicacy in the adjustment. Also, if desired, after the hour-glass hasturned on its arms 1 so as to bring part 6 uppermost, the flow of theemery may be expedited by turning the plate 11 until the thin edge oflug 13 registers with numeral 1 to allow the maximum fiow of materialfrom a to Z).

Any suitable materials may be used for any of the parts above describedand they be fashioned or shaped of any desired number of pieces andassembled in any suitable, convenient and desired manner. I preferhowever to use celluloid for the hourglass container or some otherlight, transparent or nearly transparent non-frangible plastic material.

Minor changes be made in the construction, combination and arrangementof the several parts of my invention, of which only a preferred form isshown and described herein, without avoiding the spirit thereof, and itis my intention to include all such in the appended claim which it is mydesire shall be given the broadest construction consistent with itswording.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

In culinary alarms, an integral hourglass, a pivotally mounted plateoscillating in a transverse opening in said hour-glass at the narrowestpoint of the passage between the two parts of the latter, provided witha tapering arcuate slot and adapted to be 0scillatedto bring any desiredpart of said slot into register with said passage, and means integralwith said hour-glass and between which the plate is secured foroscillatory motion.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.

ADA ROBERTS.
